| Abstract | ||
| A field experiment was conducted in one of the fields in Nineveh Governorate, in soil texture was clay silty loam, under the axial sprinkler system, where the research included studying the effect of (two levels of soil moisture (13-15%), (17-19%), two depth of tillage (12-14 cm) and (15-17 cm), and three types of chisel plow-share (conventional share, the spearhead and the severed share)), on the following field indicators (draft force, soil adhesion force, the tillage appearance through (number of clods with a diameter larger than 7.5 cm) and the vertical deviation ratio to tillage depth). This experiment was implemented with split-split plot under randomized complete block design (RCBD) with three replicates. The results showed that the lowest draft force, adhesion strength, number of clods, and the lowest vertical deviation ratio to tillage depth were recorded in the soil moisture content (13-15%), the depth (12-14) cm recorded the lowest draft force, adhesion strength and a number of clods, while it outperformed depth (15-17) cm in obtaining the lowest ratio of vertical deviation, as the severed share outperformed in obtaining the lowest draft force, adhesion strength and a number of clods, while the spearhead share outperformed in obtaining the lowest ratio of vertical deviation, achieved interaction between the soil moisture content (13-15%) and the depth (12-14) cm, the lowest draft force, adhesion strength and a number of clods, while the interaction between the soil moisture content (13-15%) and depth (15-17) cm achieved the lowest ratio of vertical deviation. | ||
